SPECIFICATION forming part of Letters Patent No, 661,752, dated November 13, 1900.

Application filed June 9, 1899; Serial No. 719,993. (No modelthe accompanying drawings, is a specitica-.

tion, like letters and numerals on the drawings representing like parts.

This invention relates to that class of looms wherein provision is made for changing shuttles automatically.

The loom to be herein described contains a spare or auxiliary shuttle feeder occupying normally its inoperative stationary position at the 100m side; a lay carrying a running or active shuttle-and having at its ends a horizontal alining-surface coincident with the race of the lay, said surface supporting the running or active shuttle when its direction of motion is being reversed, and also a back wall to constitute a support or alining-surface for the rearside of the running or active shuttle to aline it with the reed; averticallymovable front plate to contact with the front side of said shuttle asit comes upon and leaves the alining-surface coincident with the race of the lay; an indicating mechanism to determine when a running or active shuttle should be changed; means controlled as to its time of movement by said indicating mechanism to raise and lower the said front plate vertically, it being put into position to leave an open passage to said back wall when the running or active shuttle is absent from the feeding end of the raceway of the lay and occupying a position opposite said'back wall during the regular operations of the loom after a spare shuttle has been supplied to the race of the lay instead of the ejected running or active shuttle, said front plate remaining in said position while the shuttle put on a spare-shuttle feeder is being thrown as the running shuttle; means to actuate the sparesh uttle feederso that itmay meet and partake of the movement of the lay in order that the spareshuttle may be fed onto the alining-surface of the lay when the front plateis put into position to uncover the way to said back wall and so that the shuttle-feeder may put and press said spare shuttle against the back .wall of the lay, and means to throw the spare shuttle across the lay, the front plate being put into position directly opposite the back wall after the spare shuttle has been thrown across the lay from its position between the back wall and spareshuttle feeder, the latter retiring from the lay before the return of the spare shuttle to the feeding end of the lay, it thereafter becoming the running or active shuttle and coming into and going from between the back wall and the front plate then directly opposite and contacting with both sides of the shuttle.

The front plate of the lay referred to is attached to a front-plate carrier which in its movements does not, as'heretofore, traverse vertically the path of the shuttle in coming on and off the horizontal alining-surface of the lay, and, as herein shown, saidfront plate depends from a plate-carrier which overhangs the back wall and crosses the lay above the path of travel of the shuttle, and to supply a spare shuttle to the horizontal alining-surface of the lay coincident with the level of the race thereof the frontpl'ate is simply moved 'ertically to afford opportunity for the spare shuttle to come into working position on the lay and be pressed against the back wall.

In the loom to be hereindescribed it is supposed that the ejected running or active shuttle will be discharged from the loom at the end of the raceway opposite that upon which the spareshuttle is supplied; butI have not herein shown any particular mecha uistn for discharging or receiving the running or active shuttle, as I may use any devicescommonly employed in looms for that purpose, mypreseut invention referring chiefly to that end of the lay where the spare shuttle is put upon the lay to take the place of the running or active shuttle.

By the in vention herein described it is possible to leave the horizontal alining-surface of the lay at the end of the raceway, said aliningsurface constituting the only bottom of the shuttle-box in which both the spare shuttle and the running shuttle rest when be-' ing acted upon by the usual picker-stickabsolutely free from any cross-grooves, said alining-surface being only a picker-stick slot. Figure 1 of the drawings shows a suliicient trolled-by the.filling.such, for instance, as

- afilling-fork orother instrument common to.

portion of a loom with my improvements added toenable my invention to be understood, the lay being in its forward position and the spare-shuttle feeder being in its inoperative position. Fig. 2 shows the lay on its back stroke, the spare-shuttle feeder having been operated to put a spare shuttle onthe the movement of the operating-lever by the' indicating mechanism at, such time being about to act to lift the front plate of the lay heioperatedzin unison, and the breast-beam between its movements from the position Fig. 4=into the posit-ion Fig. 2. Fig. 5 represents a top or plan view of the feedingendof thelay, enlarged, and the back wall and front plate. Fig. 6 shows a front edge. view of the front-plate carrier andsome of its parts.

The spare shuttle o is sustained normally bya suitable support or plate 0 carried bya lever 0 having its fulcrum on the fulcrum rod c of the lay, so that said lever and support may swing coincident with the lay when afresh shuttle is to be supplied to the horizontal alining-surface ofthe lay. When thesupport c is coupled with the lay, it occupies a position substantially in alineinent with the horizontal alining-surface B ofthelay. (See Fig.2.) The lever c has a stud 0, upon which is mounted part of the shuttle feeder or supplying device, shown as composed of alever'c having at its upper end aplate 0 provided with a stud a on which is pivoted a spare-shuttle presser or hinder said plate also having ing an incline or cam d and astud or pro ject'ion disaid stud resting normally upon a suitable stud c0 extended from saidlever.

, In the normal position of theactuat-orthe upper end of the cam partof the actuator rests substantially incontaot with a projection E, common to the last'named patent and fixed with relation to the loom-frame and the support 0 carrying the spare shuttle, and the spare-shuttle feeder stands normally in its inoperative position at the loom side, as in Fig. 1, when the loom is running regularly and the filling is being supplied from the running shuttle c.

Whenever for any reason a spare shuttle lying on the supportc is to be put upon the horizontal alining surface B of the lay in place of a running shuttle c, the operation of which is to be discontinued. said spare shuttle taking the placeof and being thereafter thrown as the running shuttle, the lever e is actuated and its forward end islifted, as provided for in said United States PatentNo.

614,369, and therod a cross-barb and rods (1 and a are lifted, causing theyfront-plate carrier, as herein shown, to be raised and carry up with it the front plate or hinder b it constituting a movable front wall fora d of the actuator E and slides the same vertically on the bar o of the spare-shuttle feeder, causing the cam part of said actuator to meet the projection E and turn said bar 0 about its pivot 0 in opposition to its holding-spring d Such movement of the bar 0 causes it to strain a suitable spring 01 connected therewith and with an extension d of the lever 0 the straining of said spring causing the lever 0 havingthe spare-shuttle support, to move immediately toward the lay until the left-hand edge of the spare-shuttle supports (see Fig. 2 of the drawings) meets the right-hand edge of the aliuing-surface of the lay, thus closing up the space between saidsupport c and said alining-surface B and instantly thereafter the lever 0 forming part of the spare-shuttle feeder, by its continued movement causes its wallor binder a", resting against the front side of the spare shuttle c, to push said spare shuttle from the spare-shnttlesupport onto the horizontal alining-surface B of the layand against theupright back Wall E, and during this operation the plate o of the spare-shuttle feeder traverses substantially the supportc (See Fig.2.)

The spare shuttle is put onto the horizontal alining-surface of the lay while the carrier and front plate 17 are removed from the position opposite the back wall B, said front plate being shown as lifted in Fig. 2, this beingdone while the running shuttle is at the opposite end of thelay, where it may be taken therefrom and discharged in any usnalor suitable manner common to this class of looms.

The loom herein to be described will have an indicating device, which may be a filling fork, asprovided for in said Patent No. 61,369, and when said indicating device is moved, as it will be by the absence of filling in the shed, the lever 6 provided for in said patent, will be started at the next forward stroke of the lay immediately following that forward stroke during which the indicator or filling-fork was actuated, and during this succeeding forward stroke of the lay the.

lever e is started upwardly about as the lay arrives in the position Fig. 4 and while completing its forward movement starts upwardly the cross-bar, thus removing the carrier and the front plate from its normal op- ,erative position facing the back wall B leaving a free and clearopen space opposite said back wall and above the horizontal aliningsurface of the lay, the shuttle-box at the re- ITO ceiving'end of the lay being at such time 'scope of this invention the use of any such empty, the running shuttle to be changed havcontrivances instead of the filling-fork toining been taken care of at the opposite end'of dicate when a shuttle should be changed. the lay in'any usual or suitable manner, as I In this invention it will 'be noticed that I 7 stated, and by the time that the lay arrives at have dispensed with 'what is designated in its second forward stroke or the'stroke next United States Patent No. 614,369 as a minfollowing thatin which the indicating apparahing-shuttle box, it acting to lift the running 1 tus or filling-fork was moved, orjust after the shuttle to be discharged from the raceway at laysta-rts back again, the actuator E,tl1r0l1gh theend of the lay at which it was received; 75
